Choriocarcinoma a rare malignant neoplasm of trophoblastic tissue, is characterized by early blood borne metastasis to distant organs such as lung, liver and brain. Involvement of central nervous system by metastatic choriocinoma may be manifested as acute or subacute apoplexy due to vascular invasion with tumor emboli. Therefore the diagnosis of cerebral choriocarcinoma should be suspected in women of child bearing age presenting the signs of acute or subacute intracranial pathology. We present and discuss 2 cases of intracerebral metastatic choriocarcinoma simulating cerebrovascular accident. One case, a 35 years old Korean housewife, was admitted to the department of neurosurgery, Kyung Hee University Hospital, with the chief complaints of headache, vomiting, focal seizure and right sided hemiplegia for 2 weeks duration. She had a history of irregular vaginal bleeding from 3 months before admission. On admission, there were flaccid paralysis of the right extremities with right sided facial palsy, central type and neck stiffness in moderate degree. Gynecologically, round tumor mass about 1.5cm in size at vagina was palpable and urine HCG was positive. Chest X-ray film showed scattered multiple nodular densities at both lung fields. Carotid angiogram showed vascular tumor in the fronto-parietal region. Brain scan revealed increased uptake in the parietal area. She died suddenly 3 days later at home. Another case, 39 years old housewife, was admitted to the hospital with unconscious state. Although she had and operation of hysterectomy 5 months before admission due to massive vaginal bleeding, she was quite well till several hours prior to admission when she complained of headache and vomiting followed by sudden loss of consciousness. Neurologic examination revealed deep comatose state with full dilated and fixed pupil. Chest film showed several nodular densities at both lung fields. Carotid angiogram revealed avascular space occupying lesion at right posterior partietal region. On operation, Dura was tense and scanty subdural hematoma and massive brain swelling were identified and intracerebral hematoma estimated 80cc was evacuated. Atypical trophoblast was found microscopically from biopsy material. She died on the 2nd postoperative day.
